Abstract
The viscosities of molten CaO-SiO2-CaF2, -MgF2, -BaF2 systems have been measured at 1450°∼1600°C by viscosimeter “Rotovisko”, following therotating cylinder method. From the results it has been shown that these melts behave as Newtonian fluids, and that the relation between viscosity coefficient and temperature is expressed by an Arrhenius type equation.The viscosities of the melts are independent of the kind of fluoride in case of the equimolar composition.The addition of fluoride causes the lowering of the viscosity coefficient, and this effect is significant in acid melts, but not remarkable in basic melts.In the acid melts, this phenomenon is discussed in terms of the reduction of the flow unit. Then, the possible reaction between silicate anions and fluorine ions is suggested as follows:(This article is not displayable. Please see full text pdf.)
